Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 7; Anal soft rays: 16 - 17; Vertebrae: 40 - 42. Distinguished from its congeners, except for P. carnosus and P. moeschii, by the presence of an enlarged and prominent process of the post-temporal (the "supraclavicular process" of previous authors), which is almost as long as the post-cleithral process; the presence of long hair-like epithelial projections on the skin and long tubular extensions of the sensory pores. Differs from P. carnosus and P. moeschii in having very well developed procurrent caudal rays that are sinuously curved along the anterior edges. Can be further distinguished from P. carnosus in having a rounded (vs. pointed) tip of the nuchal shield and from P. moeschii in having a deeper body (16.5-16.7% SL vs. 13.0-14.5) and lacking lighter colored patches on the body (Ref. 54514).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00832 (0.00384 - 0.01800), b=2.95 (2.77 - 3.13), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.4 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
